I get paid money by writing performant high level code for real-world hardware. Now I can pay someone else money to write barely funtional assembly for made up hardware. 10/10 (Okay for real, if you're the kind of person who disappears into YouTube rabbit holes of retro game code, this game is literally made for you)

Very elegant coding game in a pseudo-assembly language. Some real brain-busters in here, as well as a sandbox to play around with the mechanics, and a bit of a hidden narrative to explore. Zachtronics is known for programming puzzle games and this early title has all the magic in text-only form,

This isn't just a game teaching you assembly programming. It's a puzzle. While the puzzles start out deceptively simple (no doubt for those not yet versed in assembly programming), they soon grow more complex and amusing, and the tesselation of the TIS-100 becomes relevant. Each node contains extremely limited memory and a limited number of instructions. With hard limits on how much control flow you can stuff into each node, you'll eventually have to learn how to take advantage of the TIS-100's "tesselated" processing by dividing the work among nodes, especially if you want to try to write fast, elegant programs. Whether you're a programmer or not, this is a playground for your brain. You might get all the way through and spend hours optimizing your programs for achievements and giggles, or you might get stuck after a few puzzles and walk away having learned at least the basics of what assembly programming looks like. The difficulty curve seems well-designed and should be fun for a variety of skill levels.

It's a game where the gameplay is programming. If you like programming, you might like TIS-100. If you don't like programming, you probably won't like TIS-100.
